Add ANGLE as a 3rdparty library to Qt.

ANGLE is a component that implements the OpenGL ES 2.0 API on
top of DirectX 9. See the following for more info:

http://code.google.com/p/angleproject/

ANGLE is now the default configuration on Windows. If you
want to use desktop OpenGL, you should build Qt with the
following configure options:

    -opengl desktop

To configure Qt to use another OpenGL ES 2 implementation,
you should use:

    -opengl es2 -no-angle

Task-number: QTBUG-24207

+# We need to call syncqt manually instead of using "load(qt_module_headers)" for several reasons:
+#  1) qt_module_headers assumes the TARGET is the same as the include directory (eg: libGLESv2 != GLES2)
+#  2) If we made a 'QtANGLE' module, the include directory would be flattened which won't work since
